According to Jin10, QUICK FactSet data showed that ChangXin Memory Technology's EBIT margin reached 82% in the second quarter of 2026, surpassing SK Hynix's 76% and Samsung Electronics' semiconductor business at 70% to become the most profitable memory chip maker in the period. Its revenue rose about tenfold from a year earlier, the fastest growth among ChangXin Memory Technology, Samsung, SK Hynix, Micron, Kioxia, and SanDisk. Analysts said the margin increase was closely tied to changes in supply and demand in the memory chip market, as Samsung, SK Hynix, and Micron devoted more resources to high-bandwidth memory for AI servers, tightening supply of standard DRAM and pushing DDR5 prices sharply higher.
